GALVESTON HARIV ELL, OF OARTERSVILLE, GEORGIA.

COTTON CHOPPEFl AND CULTIVATOR.

SPECIFICATION forming part of Letters Patent N0.'762,714, dated une 14,1904.

Application filed `Ianuary 10, 1903. Serial No. 138,565. (No model.) v

To @ZZ whom it may/ 'concern:

Be it known that I, G ALvnsToN HARWELL, a

citizen of the United States, residingat Carr tersville, in the countyofBartow and State of Georgia have invented a new and useful Cotasdesired.

With these various objects in view the invention consists in the novelfeatures of construction and combination, all of which will be fullydescribed hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure l is aperspective view of the combined cotton chopper and cultivator con--structed in accordance with my invention.V

Fig. 2 is a side view of the same. Fig. 3 is an inverted bottom planview. Fig. 4 is a rear end View showing the manner of connecting andoperating the chopping-hose, and Fig. 5 is a detail view illustratingthe manner of connecting the shanks of the hoes.

In carrying out my invention I employ a main frame A, which isessentially rectangular in shape and preferably constructed of suitablebar-iron, a clevis A' being arranged at the forward end for theattachment of a suitable draft. (Notshown.) BracketsBare attached to theside members of the frame A midway their length, and journaled in saidbrackets is a horizontal shaft C, carrying the mounted or supportingwheels D at their outer ends. Oppositely-disposed bevel-gears E aremounted upon the shaft or axle C, said gears meshing with bevel-gears F,mounted upon the forward ends of the shafts Gr, which are journaled insuitable bars H, arranged upon cross-beams H', connecting the saidmembers of the frame adjacent to the rear end, and upon the rear ends ofthe shafts G are the crankdisks I, having adjustable wrist-pins I', towhich are connected the pitmen K, which pit- 'men K being connected tothe crank-armL are rigidly connected to the forward ends of therock-shafts M, said shafts being journaled in suitable bearings M',suspended from the main frame, and attached to the said rockshafts M arechopping-hoes N, the shanks N' passing through the perforated ears O' ofthe clamping-clip O, said clip beingvsecured to the rock-shaft M bymeans of a set-screw O2, and it is obvious that by passing the shankthrough the perforated portions of the clip the set-screw willeffectively bind the rockshaft M against the shank of the choppinghoes,as most clearly shown in Fig. 5.

As the device is drawn forwardly the axle or shaft O will operate thebevel-gears E, which in turn will rotate the gears F and shaft G, and asthe crank-disks I are rotated the pitmen K will be reciprocated and willimpart a rocking motion to the shafts M, and the chopping-hoes N willthus be made to chop the cotton-plant at the point where it is desiredand thin out or cut away the said plants. By loosening the set-screw O2the chopping-'hoes can be quickly and easily detached from therock-shaft M.

In order to provide for the cultivating of the cotton, I employ thedepending tubular standards P, .which are connected at their upper ends4to the cross-beam P', secured to the main frame intermediate thecross-beam H'. rIhe cultivator-teeth l?2 are provided with suitableshanks P3, which are inserted in the lower ends of the tubular standardsP and are securely fastened by set-screws I.

Handles Q are secured to the upper ends of the brackets B and are bracedby suitable bars Q', extending from the handles to the rear end of themain frame. The frame is supported in this proper horizontal position bymeans of the depending legs R, carrying the caster-rollers R' at theirlower ends, which legs have a spring-arm S, connected thereto, and thefree end of each'spring-arm works in a guide S', attached to the rearend of the frame at the under side thereof, thus permit- IOO ting acertain amount of yielding movement for the supportinglegs and rollersin order that they may accommodate themselves to the irregularities ofthe ground over which the machine is moved. It will also be noted thatthe bolt S2, which secures the brace Q', also serves to secure the guideS.

If desired, the main frame A may also be strengthened by means oflongitudinal beams A2, extending from the front end of the frame to thecross-beam P.

It will thus be seen that I provide an eX- ceedingly simple andefficient construction of f connected to one of the shafts, and meansfor rotating the disks.

2. In a device of the kind described the combination with the mainframe, a gearing device arranged thereon, bearings connected to the rearend of the main frame and depending therefrom, rock-shafts journaled inthe said bearings, crank-arms attached to the forward ends of therock-shafts, pitmen connected to the crank-arms, crank-disks havingadjustable wrist-pins to which the upper ends of the pitmen areconnected and the shafts to which the crank-disks are connected, saidshafts being journaled upon the main frame and-operated by the gearingdevice arranged thereon, and choppinghoes having their Shanks or handlesdetachably connected to the rear ends of the rock-shafts, as specified.
